Could no longer use our window AC units in the new windows so went looking for replacement AC and explored the portable version. This unit received good reviews. Setup one unit the other day and relatively simple to do. Tested the unit afterwards and was impressed by the cool air delivery and short time it took to reduce the temperature in the large open living room. Have not tried the unit on a humid warm day yet as our weather has not been like that to this point. Bought 2 of these units to setup in opposite ends of a large single story ranch home with approx. 1400 sq ft of floor space. May end up closing doors of a couple of currently unused rooms to reduce sq footage to cool since those areas don't need cooling.
